Enum MemError 

pub enum MemError {
    Uninitialised {
        addr: i64,
    },
    Misaligned {
        addr: i64,
    },

}

Something went wrong with a memory access.

Variants

Uninitialised

Read of memory that was never written.

Fields

addr: i64

The offending address.

Misaligned

Access not aligned to a word boundary.

Fields

addr: i64

The offending address.

NotAByte

A tryte outside 0..=255 was written to a byte-oriented device (D-04).

Fields

value: i64

The offending value.

Device

A device rejected the access.

Fields

addr: i64

The address accessed.

reason: &'static str

What the device reported.

AddressOverflow

The access would run off the end of the address space.

Fields

addr: i64

The base address of the access.

len: i64

How many trytes the access needed.

Implementations

impl MemoryError

pub fn overshoot(&self) -> Option<i64>

For an AddressOverflow, how many trytes past the end of the address space the access would have reached. None for the other variants.

Trait Implementations

impl Clone for MemoryError

fn clone(&self) -> MemoryError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for MemoryError

impl Debug for MemoryError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for MemoryError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for MemoryError

impl Error for MemoryError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for MemoryError

fn eq(&self, other: &MemoryError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
